IMPROVEMENT IN WATER-MOTOR.

The Schedule referred to in thse Letters Patent and making p artof thesame.

To all whom it may concern.-

Be it known that I, S. W. BROADWELL, of Logan,l

in the county ofHarrison, and State of Iowa, have in- 'vented anImprovement in the Construction of Water- Motors; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, which will enable .others skilled in the art to make and usethe same, reference being had to the accompanying drawings and lettersmarked thereon, making a part of this description, in which- Figure l isa perspective representation of a motor, showing my improvement.`

Figure 2, a perspective representation o f, one of the lower buckets,removed from the walking-beam.

The present invention relates to an improvement in that class of motorswhich has buckets lnmg to an oscillating walking-beam, which operateslevers for opening and closing valves in the iiu'me above; and

Its nature consists inthe novel construction of parts as hereinafterfully shown.

A represents a Hume, which is to be placed in the bed of' a creek orstream, .where there is a fall suieient to clear the buckets G G,andwhich has bulkheads B, extending down-stream far enough to provideroom for valves T, which operate therein, to have seat-room below thegates H.

The fiume and bulkheads are vsupported with posts O, which have a iirmsupport in the tail-race A' below, or bed of the stream, as'the case maybe.

. 'Beams D are rigidly fastened to the posts C and t0 short posts E,(the latter, also, being supported in the race A,) in order to provide`aiirm support for the ,shait F of the'walking-beam.

This beam consists of a shaft, F, two bars, I, so

placed on the shaft as to have their ends balanced,

and two ties, h, fastened to the bars in such position as to be directlyunder the gate-rods K.

To the ends ofthe bars I are hung buckets G, which -alternately catchwater discharged from the bnikheads B, and discharge it by means ofvalves S, iig. 2, fastened to rods J, which strike against bumpers Z',in the bottom ot' the race A', and raise said valves ofi` from theirseats jQ-the lower ends of' the rods having bearings in guide-platesd,attached to and projecting below the buckets, V-and their .upper endshaving bearings in guide`plates N, fastened tothe top edge ot' thebuckets, and projecting down Vinto them, and so held in place as to havean easy vertical motionv as the valve S is opened and closed.

' The object of placing the plates N below the tops of the buckets, isto prevent themfrom. turning the water over their top edges, whenfalling from the bulkheads B.

This arrangement requires that the plates d be made to project below thevalve-seats j, iii-order to place the bearings of the rod J theproperdis-` tance apart, and also for the free escape of the water.

The valves T, iig. l, have seats inv the bottoms of the bulkheads B, andare so weighted as to keep the rods Z, to which they are attached, in anupright position. i*

These rodshave bearings in plates n, attached to bridges W, which arefastened to the bulkheads B, and to their upper ends are fastenedadjustable nuts V, by means of which the slotted ends lof the levers Lare made to raise the valves T.

These levers have slots'm, asshown in an enlarged drawing, madevertically through them, to receive pins projecting up from bearings x,which are attached to the bulkheads B.

By this means, the levers L are so held in place as to oseillate withoutbinding or cramping in any art. j p To the opposite ends-of the levers Lare fastened,

by hooks and eyes, gate-rods K, which are so Abent,

at right angles, at their lower ends, as to catch under the ties h, andalternately so draw the leversV Ldown as to open the valvesT ofbulkheadsB. I

Two gates, H, are pivoted to the bridges W, and

so inclined as to be closed by the pressure oi' the water when the motoris at rest, and to be raised `up by ropes or chains (t when it is to beputin motion, said ropes or chains being attached tothe lower edges ofthe gates, and. brought through. eye l) in the arm-standards U, andthrough a hole in a standard, Y, are both raised at the same ti1ne.

The adjustment of the valvesT on seats e'islmade by turning the nuts Yonrods`Z;"and all that is required to start the motor, is to simplyraise the gates H, by means of rupes a, and so bring down one of thelevers, L, as to raise one of the'valves, .l.

This will fillthe bucket G underneath, and, as its weight carries itdown, the tie h will strike the bent part ofthe rod K, and raise thevalve in the oppo* site bulkhead, and till the opposite bucket while theone first filledis discharging.

It .is not, however, necessary, after the buckets have been once filled,to move 'either of the. levers to start the motor, as one of the bucketsis then full enough with water to move so soon as the gates are raised.

'- The mechanism for so changing'the' oscillating Having th qs describedmy invention,

lVliat IcIaim, and desire to secure by Letters Patent of theUnitedStates, is

1. The weighted valves T, provided with adjustablenuts V, in combinationwith the slotted levers L, depending'gate-rods K,oscillating.walking-beam I F, provided with ties h and buckets G, :msdcvscribd.

2. The buckets G, provided with valves S, attached to rods J, whicharemadeito discharge Water by striking bumpers Z', in the bottom of therace, and provided with plates N, which project down into them, toprevent winter from being splashed over their edges, and with plates d,which project down to form suitable bea Witnesses:
